as it turns out... this is a third-party edit. the video was mirrored and cropped, and trimmed. the subtitles were put back on. the original one is this: https://www.bilibili.com/video/BV1ND421n7HE
but it's too long for me to upload... it's over five minutes long...😬
and if anyone can't view it from bilibili, here's my google drive copy! https://drive.google.com/file/d/14fjzTU2G3MUCgNqPbYq8ZrVhZaXvUMkU/view
